Developments on unrest in the Middle East and North Africa:

SUNDAY

[LIBYA, 8:50 p.m. ET, 3:50 a.m. local] Libyan leader Moammar Gadhafi has criticized a resolution that the U.N. Security Council passed against his regime, telling private Serbian station Pink TV by phone that council members "took a decision based on media reports that are based abroad."

He added, "If the Security Council wants to know about something, they should have sent a fact-finding committee."

The resolution, passed over the weekend, includes an arms embargo, an asset freeze and travel bans for Gadhafi and members of his family and associates.

[GAZA, 3:41 p.m. ET, 10:41 p.m. local] A Palestinian militant was killed in east Gaza Sunday in an Israeli air strike, according to Palestinian medical and security officials. An Israel Defense Force spokeswoman denied that such an attack took place.

[EGYPT, 2:53 p.m. ET, 9:53 p.m. local] Officials say the Egypt Stock Exchange plans to open on Tuesday. The markets have been closed since January 27.

[LIBYA, 1:45 p.m. ET, 8:44 p.m. local] The British government said Sunday it is freezing the assets of Libyan leader Moammar Gadhafi, members of his family, and those acting on their behalf.

[LIBYA, 9 a.m. ET, 4:15 p.m. local] Protests are picking up in Libya's western city of Zawiya with former security forces who said they have switched sides and joined the opposition. About 150 people rallied outside the town in support of Gadhafi later on Sunday, in what appeared to be a hastily organized demonstration. CNN later saw a second small pro-government rally that may have been organized for the benefit of international journalists. The crisis in Libya is affecting oil prices, and how much Americans pay at the pump. To better understand why, CNN gets an explanation from an oil analyst.

The United Nations Security Council unanimously approved a draft resolution to impose sanctions against Libya amid escalating attacks on anti-government protesters in the north African country.

The resolution draft includes an arms embargo, asset freeze and a travel ban. It also refers Libya to the International Criminal Court.

[YEMEN, 12:14 p.m. ET, 8:14 p.m. ET local] Thousands of people are protesting outside Sanaa University demanding that President Ali Abdullah Saleh resign. Representatives said the youth-dominated sit-in will not budge until he leaves. On Saturday, leaders of two prominent tribal groups, the Hashid-dominated National Solidarity Council and the Baqil tribe, said they would send members to join the protests calling for Saleh's resignation. Time magazine weighs in on how long the protests in Yemen might last.

[TUNISIA, 11 a.m. ET, 5:18 p.m. ET local] Prime Minister Mohamed Ghannouchi's resignation Sunday came a day after three people were killed during protests in the capital, Tunis. "I am resigning today because I am not willing to be a person that takes decisions that could cause casualties," he told reporters Sunday. He also questioned "why a lot of people considered their main target to keep attacking the government, although a lot of its members agreed to join in this critical time."

[TUNISIA, 10 a.m. ET, 4:21 p.m. local] The prime minister of Tunisia has stepped down from the interim government, according to the country's official news agency.

[OMAN, 9 a.m. ET, 6:10 a.m. local] At least two protesters were killed and about 10 injured during clashes between protesters and police in the Omani industrial town of Sohar, according to reports from state media and Oman TV editor Asma Rshid. "The police shot them because they burned shops and cars in Sohar," Rshid said. Another source said police fired rubber bullets. A number of police had also reportedly been injured, but CNN has not been able to confirm how many.

SATURDAY

[TUNISIA, 9:12 p.m. ET, 3:12 a.m. local] Protests in Tunisia turned violent and deadly Saturday, just over six weeks after a popular uprising forced the president out of office, and lit a spark of desire for democratic reform in parts of Africa and the Middle East.

Three people were killed Saturday and nine others injured during mayhem in the capital, Tunis, according to a Interior Ministry statement cited by the state-run news agency, Tunis Afrique Presse (TAP).

More than 100 people were arrested, the ministry said, in the area around Habib Bourguiba Avenue, in the city's center, accused of "acts of destruction and burning."

[LIBYA, 4:58 p.m. ET, 11:58 p.m. local] City councils in areas no longer loyal to Moammar Gadhafi have chosen former Justice Minister Mustafa Abdul Jalil to head an interim government which will represent all of Libya, according to Amal Bogagies, a member of the February 17 Uprising coalition, and a separate Libyan opposition source.

[LIBYA, 4:40 p.m. ET, 11:40 p.m. local] President Barack Obama, in a statement issued Saturday after reports that forces loyal to Libyan leader Moammar Gadhafi had fired on civilians, said "that when a leader's only means of staying in power is to use mass violence against his own people, he has lost the legitimacy to rule and needs to do what is right for his country by leaving now."

The White House statement was  issued after Obama spoke with German Chancellor Angela Merkel.

[BAHRAIN, 9:37 a.m. ET, 5:37 p.m. local] Exiled opposition leader Hassan Mushaima has arrived back in Manama, Bahrain. Mushaima, leader of the Haq Movement, had told followers earlier in the week that he had been detained in Beirut, Lebanon.
